Well, after 5 hours, Andy and I, with the help of a fully equipped workshop with 4-point hydraulic lift, a laptop with Rovacom, and the input of my brother (who is an engineer), worked out the best way to change the rear air springs on a P38a.
The trick is, you get Nick Kerner Engineering to do it! Bloody job and a half that was!
Supposedly "half an hour from getting the axle stands out of the garage" (I'm onto you, Ron Beckett), turned out to be the second most bloody minded job I've done on a Land Rover, after fitting the badly sized steering guard to the Disco. If anybody plans on doing it themselves, come and talk to me and Andy first... or preferably Nick Kerner...
I tell you, next time something goes wrong on the damn thing it's straight into the garage with a blank cheque book :)
